Lily Munster, Countess of Shroudshire (née Dracula), is a fictional character in the CBS sitcom The Munsters, played by Yvonne De Carlo. The matriarch of the Munster household, Lily is an undead vampire. Her character was loosely based upon Vampira, who was coincidentally based upon Charles Addams's Morticia Addams.
The role was later played by Lee Meriwether in The Munsters Today. Lily was born in 1827 to Sam Dracula (Grandpa) and his 166th wife (referred to only as "Grandma"). She lived with Grandpa for some time in Transylvania before meeting Herman Munster and marrying him in 1865.
She, Grandpa, and Herman moved to America sometime before the mid-1940s and adopted her sister's child, Marilyn. In the mid-1950s she gave birth to Eddie, her and Herman's only child. Lily is the matriarch of the Munster family.
She is very close with her niece, Marilyn. She has a werewolf for a brother, who appears in one episode, and a sister who is mentioned a few times who is Marilyn's mother. Lily is the voice of reason in the Munster household, often relied upon to set problems right, and typically mediates when Herman and Grandpa squabble.
